Detailed Description
This study will be conducted using a phase I/II trial design to assess the safety and efficacy of the PD-1 antibody expressing mesoCAR-T for patients with mesothelin positive, advanced recurrent or refractory malignant solid tumors. MesoCAR-T can specifically and effectively kill the mesothelin positive cancer cells, PD-1 antibody are secreted from the CAR-T cells could improve immunosuppression microenvironment, new CAR-T cells contain the advantages of CAR-T and immune checkpoint inhibitor, which is a promising therapeutic method for advanced solid tumors.
The new CAR-T therapy is applied to clinical practice as bellow. T cells are prepared from peripheral blood mononuclear cells (PBMC) by leukapheresis, and then activated and engineered to express chimeric antigen receptors (CARs) targeting mesothelin and PD-1 antibody. Cells are proliferated in culture and returned to the patients by venous transfusion therapy. A total of 50 patients may be enrolled in the study. The total duration of the study is expected to be approximately 24 months.

Intervention / Treatment |
---|---|
EXPERIMENTAL: PD-1 antibody expressing mesoCAR-T cells
Patients will receive two cycles of PD-1 antibody expressing mesoCAR-T cells treatment.
Every cycle, peripheral blood mononuclear cells (PBMC) are collected on day -18, CAR-T cells are cultured in a GMP standard workshop.
Patients are given a three-day regimen of chemotherapy consisting of fludarabine and cyclophosphamide aimed to deplete the lymphocytes before cells infusion.
Then the patients will receive an i.v.gtt infusion of PD-1 antibody expressing mesoCAR-T cells from day 1 to day 3 (±3days).
|
Patients with mesothelin positive cancer will be infused the PD-1 antibody expressing mesoCAR-T cells.
The modified mesoCAR-T cells can specifically kill mesothelin positive cancer cells and secrete PD-1 antibody, which could enhance the cytotoxicity of mesoCAR-T cells and activate the tumor infiltrating lymphocytes.
